Techniques consistent with this invention process handwritten or hand-drawn input and speech input. Method steps include recognizing received handwritten or hand-drawn input, recognizing received speech input, and creating or modifying an electronic document according to the speech or handwritten or hand-drawn input. An apparatus includes structure for recognizing handwritten or hand-drawn input, structure for recognizing speech input, and structure for activating modes for processing the handwritten or hand-drawn input and the speech input responsive to commands in the handwritten or hand-drawn input and the speech input.

Processing handwritten and hand-drawn input and speech input

The present assembly is an ink jet printer of the continuous stream type for printing an image on a recording surface having a nozzle or orifice from which an electrically conductive ink stream is expelled by pressure along a predetermined path toward a recording surface apparatus to selectively deflect or interrupt portions of the ink stream such that the portions deflected or interrupt are prevented from reaching the area of the recording surface or which said image is printed, an ink mist shield positioned proximate to the recording surface, the mist shield being maintained at a first potential, apparatus for charging the recording surface to a second potential substantially different from the first potential whereby ink which impinges the recording surface is charged thereby and particles of the impinging ink which rebound from the recording surface are impelled toward the mist shield by the field resulting from the difference between the first and second potential. The present method, for use in a continuous stream ink jet printer for printing an image on a recording surface having a nozzle or orifice and a recording surface, and a mist shield positioned proximate to the recording surface, is the steps of expelling by pressure a continuous stream of electrically conductive ink from the nozzle toward the recording surface, selectively deflecting or interrupt portions of the ink stream, applying an electrical charge to the recording surface, such that an electrical field exists between said mist shield and said recording surface whereby particles of the ink stream which rebound upon impact with the recording surface are urged toward the mist shield.

In a moving matrix magnetic separator in which a matrix device moves relative to a processing device and a seal assembly seals a longitudinal section of the matrix device to an associated processing device, the seal assembly including a sealing surface on one of the devices and a seal on the other, the improvement comprising said seal including a base portion extending generally longitudinally in the direction of motion of the matrix device; first and second salient, resilient lip portions extending from the base portion toward an associated sealing surface in the gap between the matrix device and the processing device, and extending generally longitudinally to the direction of motion of the matrix device and spaced from each other transversely to the direction of motion of the matrix device and forming a channel therebetween; a pressurized purge fluid chamber formed by the channel and the associated sealing surface; and means for supplying purging fluid to the purge fluid chamber formed by the channel and lip portions with the associated sealing surface.

A vortical flow distributor for uniformly, vortically distributing incoming fluid in a plane transverse to the primary flow direction, including an outlet and at least one smaller inlet; a plenum chamber disposed between the inlet and outlet and having an area corresponding to the area of the outlet and having a length in the primary flow direction which is substantially less than its width; and a flow diverter aligned with each inlet for directing the incoming fluid to a plane transverse to the primary flow direction, and establishing a tangential flow with radial components for producing over the plenum chamber area a pattern of distributed vorticity which finally dissipates the flow velocity.
